Wireless rail with dynamic lighting

ABSTRACT

A lighting system is disclosed which provides dynamic lighting control of each light on a rail lighting system. The lighting system is able to change settings of each light within a track lighting or rail lighting system based on motion, user preferences, lighting conditions, or security parameters. Light intensity and color can be set and scheduled based on user control and programming. Optical sensors may also be used to provide control input for the track lighting or rail lighting.

FIELD OF THE INVENTION

This invention relates to wireless tracks or rails used to power and control auxiliary devices connected to the track or rail.

BACKGROUND OF THE INVENTION

Track lighting systems are well-known for use in interior decorating, display cases, and many other uses. Typical track lighting systems use a track having an interior channel with electrical conductors within the interior channel. Light fixtures usually include two tangs that are inserted into the track interior channel and twisted until contact is made with the electrical conductors. The tracks are normally mounted to a wall or ceiling by mounting screws.

Presently, in an installation with track lighting like in a restaurant, art gallery, or restaurant, etc., a single wall dimmer or dimmer pack is connected to one or more circuits in a lighting track. This method of connection allows all line voltage lights connected to the lighting track to be dimmed by the same amount if the same wattage lamps are used in the lights. This setup is appropriate in a situation where equal light levels are desired. However, when different levels of light are desired, the end-user must use different wattage lamps and be limited by the set lamp wattages available for a particular lamp holder, or must run multiple lighting tracks in the same space and dim accordingly. This arrangement sets limitations on the end-user and limits their creative flexibility in lighting design.

At times there arises a need for individual dimming control of separate and discrete line voltage lights, without having to run more cables and power lines or lighting tracks to each light.

Existing track lighting systems only supply power to devices but do not allow for dynamic wireless control of lighting or other devices mounted to the track.

SUMMARY

The invention has been developed in response to the present state of the art and, in particular, in response to the problems and needs in the art that have not yet been fully solved by currently available apparatus and methods. Accordingly, apparatus and methods in accordance with the invention have been developed to provide wireless control of devices and lighting along a track or rail. The features and advantages of the invention will become more fully apparent from the following description and appended claims, or may be learned by practice of the invention as set forth hereinafter.

A wireless rail system for providing power and control to auxiliary devices on the rail is disclosed. Such a system includes a one or more channels mounted to a structural building component forming a rail. Auxiliary devices on the rail communicate with each other and user devices. Each of the auxiliary devices are addressable either wirelessly or by a parallel bus within the rail. The auxiliary devices are connected and disconnected from the rail by rotating approximately 90 degrees.

A lighting system is disclosed which is able to provide dynamic lighting control of each light on a rail lighting system. The lighting system is able to change settings of each light within a track lighting or rail lighting system based on motion, user preferences, lighting conditions, or security parameters. Light intensity and color can be set and scheduled based on user control and programming. Optical sensors may also be used to provide control input for the track lighting or rail lighting.

The structure 100 may be a home, garage, workshop, shed, office building, pavilion, tent, etc. The wireless rail 106 has a first power supply 102 which feeds parallel power to the rail 106 by way of bus lines. The first power supply 102 may supply high voltage such as 120 volts or 240 volts and may additionally or alternatively supply low voltage power such as 5 volts, 12 volts, 24 volts, and/or 48 volts to the parallel bus lines of rail 106. The first power supply 102 may also supply alternating current (AC) and/or direct current (DC) to the parallel bus lines of rail 106. Auxiliary devices 104, 108, 110, 112, 114, and 116 are shown connected to rail 106. Each of the auxiliary devices may include a second power supply which is removable attached to the rail along with the auxiliary device itself. Each auxiliary device may also include a wireless communication module for both wireless communicating with other auxiliary devices and with user device 118. Each communication module may use a single or multiple communication technologies in combination. For instance, controller 104 may use a WiFi or SureFi signal to communicate with a user device or network and also use Bluetooth to simultaneously communicate with other auxiliary device connected to the rail. Controller may also use bus lines as an antenna to wirelessly communicate with user device 118 or another wireless device not on the rail and/or other auxiliary devices on the rail which may or may not share a direct electrical connection to a common antenna bus line. Auxiliary devices on the rail may be used to auto-tune a common bus antenna on the rail by providing dynamic reactance to the common bus antenna on the rail. A common bus antenna may be a ground line, power line, or data line of the rail bus. Digital and analog control signals may also be transmitted along a ground line, power line, or data line of the rail bus. Auxiliary devices along the rail may communicate by bus line or by wireless transmission or by a combination of both. User device 118 may be a laptop, cellular telephone, ipad, ipod, or any other device capable of wireless communication. Auxiliary devices may include controllers, computers, monitors, lighting, power receptacles for all types of power and voltage levels, cameras, microphones, speakers, fans, heaters, air conditioners, appliances, transceivers, wireless memory storage, lifters, air compressors, smoke detectors, carbon monoxide detectors, alarms, security systems, home automation controllers, and/or motion sensors.

FIG. 2 shows an assembly 200 comprising an example of a wireless rail 214 installed in an attic area 202. Wireless rail 214 is bolted to joists 204 using fasteners 206. The wireless rail is bolted to joists for increased load capacity. In FIG. 2, a user 210 used his cellular telephone to lower wench 218 allowing stairs 212 to become accessible. His cellular phone may have used Wifi or Bluetooth to communicate with controller 220 or directly with wench 218. Next user 210 desires to lower platform 208 and access items on the platform. The user then uses his cellular phone to lower two wenches simultaneously to lower platform 208. The user also uses his cellular phone to control the attic light which is located on wireless rail 214. Controller 220 may include a wireless memory storage and allow computers and other auxiliary devices along with the auxiliary devices on the wireless rail to use the memory.

For example, user 210 may store 10,000 home videos on the wireless memory storage located on the wireless rail in the attic space and my retrieve the videos on demand from within the user's home or office. The rail provides a convenient source of power and accessibility for all devices on the wireless rail.

Controller 416 may include a motion sensor, optical sensor, camera, or microphone for enabling dynamic control of the lights on the rail. For example, a person may walk across a room and lights may turn on or increase in brightness based on a direction of motion of the person. A camera or optical sensor may detect a change of lighting in a room due to cloud cover and automatically increase specific lights based on a predetermined lighting threshold in a specific area of a room. Each light may be removable by turning the light 90 degrees. Each light may be individual configured by a user or home owner according to user preferences. A user lighting schedule may be set for each individual light or for a group of lights. Each light may communicate directly with a user or with controller 416 wirelessly.
